GATE.

SPECIFICATION forming part of Letters Patent No. 260,643, dated July 4,1882,

Application tiled April 10, 1882. (No model.)

To all whom it may concer/n Be it known that I, JACOB E. BLACKBURN, ofFredericktown, in the county of Knox and State of Ohio, have inventedcertain new and useful Improvements in Gates; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertainsto make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, andinwhich- Figure 1 is a side elevation of my improved gate. Fig. 2 is'aperspective detail view of the hinge-post with its appurtenances, on anenlarged scale. Fig. 3 is a similar view ofthe latch-post with itsadjustable latchbearing and holding-plate. Fig. eis aperspectiveviewy ofthe latch-bearing detached. Fig. 5 is a sectional view of the front endof the gate with its spring-latch and latch-cap. c Fig. Gis aperspectiveview of the rear end of gate. Fig. 7

is a detail view of the upper bearing for'the pivoteil hinge-bar. Fig. 8is a perspective detailview of the adjustable shouldered hingeloop Fdetached from the gate; and Fig. 9 is a horizontal sectional viewthrough the said loop, hinge-bar, and gate-bar on the line indicated bythe letters a' x in Fig. 1.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to swinging gates; and it consists in theconstruction and ar rangement of parts of the hinge, substantially as.hereinafter more fully described, for the purpose of working, elevating,fastening, and preventing sagging of the gate to which my improvement isapplied.

In the accompanying two sheets of drawings, A represents the hinge-post,and B the latchpost.

C is a bearing which is cast upon or made in one piece with a screw, c,which is screwed into post A near its top.

D is a ilattened bar, of east-iron or wroughtiron, about two feet andtwo inches (more or less) long between its top and bottom shoulders, dd, by which pintles are formed, the upper one of which is inserted intothe top bearing, C, while the bottom one is stepped into a bracket orrest, E, which is fastened upon the l post by suitable wood-screws@ rlheflattened bar D has a series ot' shifts or notches, a a, extendingbetween its shoulders, which are adapted to receive a casting composedof a ,flattened loop, F, having a screw threaded shank,f, and shoulderse e. The loop Frides upon bar D, and isot' such a width'that it will tinto any one of the notches a.,

Upon the end piece, G, of the gate is screwed a small casting, g, whichis made with a rectangular slot or opening adapted, to flt theshouldered end ot' the loop F, which may be tightened up against it bymeans of a nut, H, having a handle, h, which said nut works upon theouter end ot' the threaded shankf, that is inserted through aboreniadein the end post, G.

Byloosening the nut H'shankfmay be withdrawn some distance through itsbore',rthereby releasing loop F from that of the notches a with whichfor the time being it is engaged, and enabling it to be slid up or downupon bar D, according to whether it is desired to raise or lower thegate. The proper elevation ot' the latter having been determined, theloop F is again interlocked by tightening up the nut H h with itsappropriate notch in bar D.

restsJ i, by which it is screwed Aupon post A. This bar is of roundiron, and isclasped by au open loop, J, the shank of which is insertedthrough the end post of the gate and nutted thereto, so as to hold itrigidly in position. By making this loop open it is prevented frombinding upon bar I, on which it rides, as its ends may be spread alittle, lit' desired, and thus vcause it to be moved easily up or downupon the bar.

Instead of fastening the several parts C, E, and I upon or in the post,they may be attached to a board or plank of suitable length, width, andthickness, as shown at A', which is in turn fastened to the post by thescrews of the several parts, which should project a sufficient distanceon the other side of the board for that purpose.

The latch-post B has a longitudinal mortise or recess, which is facedwith a ilanged plate, b, having a series of 'I1-shaped slots, b b. Thelatch-bearin g, which is preferably made of castin one piece-Wiz., therounded part or bear- I is an iron bar, cast with top and bottom iron,consists essentially of three parts, cast ing proper, (marked K,) whichhas a transverse groove or notch, I, in its middle, aplate, L, whichextends from the middle of said partin a downward direction, and anotherplate, M, extending back of part K at right angles to plate L, and madewith shoulders m m, one on each side.

The latch-bearing, constructed as above described, may be inserted intoany one Aot" the T-shaped slots b', and held in place therein by passingthe shank or narrow part of plate M in front of the shoulders m m downinto the stem or vertical slot of its appropriate opening b', theshoulders preventing the withdrawal ot' the bearing from the slot, whilethe bottom plate or extension, L, impingng upon the face of the flangedplate b and confined between its ianges, prevents tilting ot' the deviceand holds it in its proper position for engaging with the latch.

The latter is operated by a handle, N, and spring O, aud is confined atits upper end within a cupshaped cap, P, which serves the triple purposeof forming a rest for the front end of the gate, (upon the rounded partK ot' the latch-bearing,) of conining the play oi' the spring-latch, andof protecting the latter, iu a measure, from snow or dirt.

The gate is prevented from sagging by a pair of iron rods, Q, whichextend obliquely from the head of the gate to the middle of its bottom,to which their lower ends are fastened by a bolt passing through themboth, and also through the bottom rail or rails and vertical middlebrace of the gate. The flattened upper ends ofthe brace-rods are bent ordoubled around the end post, G, underneath the casting g, and held inplace by staples lc. At the opposite end ot' the gate are thebrace-boards R, which are secured on the gate by bolts or nails and attheir lower ends stepped into the lower end of the vertical middlebrace.

This gate, it will be seen, can be adjusted between its posts so as tokeep it clear of' snow or other obstructions in the road. It can beelevated to such a height that fowls and small stock may pass under it,and, whatever its position, it cannot be thrown from its hinges bystockpassingnnderit. Aftereachadjustment ot'the hinge-loop F thelatch-bearing K L M is ot' course adjusted at a corresponding elevationin one ot' its slots b', so as to hold the gate in its proper horizontalposition between posts A and B.

The rest or bracket E, into which the lower end of bar D is pivoted, maybe cast with or upon a screw in like manner as the top bearing, C, andthus screwed into the face-plank A and post A, instead of fastening itthereto by separate screws.

Having thus described myinvention, I claim and desire to secure byLetters Patent of the United States- In a gate, the adjustablehinge-loop F, having screw-threaded shankfand shoulders ce, nut H,having handle h for turning it, and the gate having perforatedend post,G, and hollow casting g, adapted to receive and fit the shouldered endof loop F, constructed and combined substantially as and for the purposeherein shown and set forth.

In testimony that I cla-im the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

JACOB E. BLACKBURN.
